Coulter, the controversial conservative commentator, appeared on an outdoor set with host Chris Matthews -- and also with dozens of supporters and detractors waiting to ask questions. But there was another person waiting to pose a question to Coulter: Elizabeth Edwards.

According to an Edwards campaign aide, Elizabeth Edwards wanted to call into the show when she heard that Coulter would be taking questions, and she called a Hardball producer to get the phone number needed to dial into the show. The result is the exchange below:

Chris Matthews: You know who's on the line? Somebody to respond to what you said Edwards yesterday morning -- Elizabeth Edwards. She wanted to call in today we said she could. Elizabeth Edwards go on the line you're on the line with Ann Coulter

Elizabeth Edwards: Hello, Chris.

CM: You wanna say something directly to the person who's with me?

EE: I'm calling you … in the south when we -- when someone does something that displeases us, we wanna ask them politely to stop doing it. Uh - I'd like to ask Ann Coulter -- if she wants to debate on issues, on positions -- we certainly disagree with nearly everything she said on your show today -- um but uh it's quite another matter for these personal attacks that the things she has said over the years not just about John but about other candidates -- it lowers our political dialogue precisely at the time that we need to raise it. So I want to use the opportunity … to ask her politely stop the personal attacks.

Ann Coulter: OK, so I made a joke -- let's see six months ago -- and as you point out they've been raising money off of it for six months since then.

CM: This is yesterday morning, what you said about him.

AC: I didn't say anything about him actually either time.

EE: Ann, you know that's not true. And once more its been going on for sometime.

AC: I don't mind you trying to raise money. I mean it's better this than giving $50,000 speeches to the poor.

EE: I'm asking you

AC: Just to use my name on the Web pages…

EE: I'm asking you politely…

AC: … but as for a debate with me, um yeah, sure. Yeah, we'll have a debate

EE: I'm asking you politely to stop personal attacks.

AC: How bout you stop raising money on the Web page then?

EE: It didn't start it did not

AC: No you don't have cause I don't mind

EE: It did not start with that you had a column a number of years ago

AC: OK, great the wife of a presidential candidate is calling in asking me to stop speaking

EE: You wrote a column a couple years ago which made fun of the moment of Charlie Dean's death, and suggested that my husband had a bumper sticker on the back of his car that said ask me about my dead son. This is not legitimate political dialogue.

AC: That's now three years ago

EE: It debases political dialogue. It drives people away from the process. We can't have a debate about issues if you're using this kind of language.

AC: Yeah why isn't John Edwards making this call?

CM: Well do you want to respond and we'll end this conversation?

EE: I haven't talked to John about his call.

AC: This is just another attempt for –

EE: I'm making this call as a mother. I'm the mother of that boy who died. My children participate -- these young people behind you are the age of my children. You're asking them to participate in a dialogue that's based on hatefulness and ugliness instead of on the issues and I don't think that's serving them or this country very well.

APPLAUSE

CM: Thank you very much Elizabeth Edwards. Do you want to -- you have all the time in the world to respond.

AC: I think we heard all we need to hear. The wife of a presidential candidate is asking me to stop speaking. No.
